Subject: GNU Parallel 20110722 ('Murdoch') released

GNU Parallel 20110722 ('Murdoch') has been released. It is
available for download at: http://ftp.gnu.org/gnu/parallel/

New in this release:

* niceload: --hard will suspend a program if a limit is reached - as
  opposed to just slowing the program down.

* niceload: --soft will slow the program down - as opposed to
  suspending the program completely.

* niceload: --run-io will slow down a program if disk io goes above a
  certain limit.

* niceload: --run-load will slow down a program if loadaverage goes
  above a certain limit.

* niceload: --run-mem will slow down a program if free memory goes
  below a certain limit.

* niceload: --run-noswap will slow down a program if the computer is
  swapping.

* niceload: --start-io, --start-load, --start-mem, --start-noswap will
  defer starting a program until the system is below the limit.

* --io, --load, --mem, and --noswap sets both --run-* and --start-*.

* niceload got a major rewrite and is now object oriented.

* GNU Parallel was presented at Nordic Perl Workshop 2011.
  http://conferences.yapceurope.org/npw2011/talk/3416

* Blog post about zcat and GNU Parallel. Thanks to Dr. John.

* 2 blog posts in Japanese. Thanks to Negima.

* Bug fixes and man page updates.


= About GNU Parallel =

GNU Parallel is a shell tool for executing jobs in parallel using one
or more computers. A job is can be a single command or a small script
that has to be run for each of the lines in the input. The typical
input is a list of files, a list of hosts, a list of users, a list of
URLs, or a list of tables. A job can also be a command that reads from
a pipe. GNU Parallel can then split the input and pipe it into
commands in parallel.

If you use xargs and tee today you will find GNU Parallel very easy to
use as GNU Parallel is written to have the same options as xargs. If
you write loops in shell, you will find GNU Parallel may be able to
replace most of the loops and make them run faster by running several
jobs in parallel. GNU Parallel can even replace nested loops.

GNU Parallel makes sure output from the commands is the same output as
you would get had you run the commands sequentially. This makes it
possible to use output from GNU Parallel as input for other programs.

You can find more about GNU Parallel at:
http://www.gnu.org/software/parallel/

= About GNU SQL =

GNU sql aims to give a simple, unified interface for accessing
databases through all the different databases' command line
clients. So far the focus has been on giving a common way to specify
login information (protocol, username, password, hostname, and port
number), size (database and table size), and running queries.

The database is addressed using a DBURL. If commands are left out you
will get that database's interactive shell.

Databases Using DBURLs, ;login: The USENIX Magazine, April 2011:29-32.


= About GNU Niceload =

GNU niceload slows down a program when the computer load average (or
other system activity) is above a certain limit. When the limit is
reached the program will be suspended for some time. If the limit is a
soft limit the program will be allowed to run for short amounts of
time before being suspended again. If the limit is a hard limit the
program will only be allowed to run when the system is below the
limit.
